iDOS, the DOS emulator app for the iPad that debuted in October and disappeared from the App Store shortly afterward, has become available in the App Store again with an update that removes its ability to store and run files installed through the iTunes File Sharing feature.
With iDOS 1.0, it was possible to install and run Windows 3.0 and much more. The loss of the iTunes File Sharing feature severely reduces the app’s utility, preventing users from easily loading their own games and other files for use within the app. Though given Apple’s prompt move to remove the app on the same day it was released, this functionality was clearly a violation of the App Store guidelines.
Version 2.0.1 of the app list the following changes, along with a clear warning from its developer, FastIntelligence:
+++ ITUNES FILE SHARING IS OFF +++
+++ THINK THRICE BEFORE UPDATE +++
– bug fixes
– Game control improvements
– Add new games
– update credit page
If you value the ability to load files of your choosing for use within iDOS, you should avoid updating the app. While iTunes does not offer an automated way to avoid updating a specific app, there is a way around this. Though exceptionally tedious in the long run, you can simply avoid downloading the iDOS update within iTunes by choosing to download all updates for your other apps individually. Needless to say, this could result in accidentally updating iDOS in the future if you’re not careful to continue downloading app updates individually.
TouchArcade points out that there is another way to still be able to load your own files for use even within the updated 2.0.1 version of iDOS using an application available for both the Mac and Windows called iPhone Explorer. iPhone Explorer is a free utility and does not require that your iPad be jailbroken in order to use it. In case you’ve already updated iDOS or simply don’t want to go through the hassle of avoiding the update, this method is an excellent option.
